  1. Advanced Networking Collaborations at SLAC Presented by Warren Matthews at the ESCC Meeting, BNL, NY, June 2001

  2. Overview • Theme: Internet2 Collaboration • Monitoring • PingER, Surveyor, RIPE, AMP, NIMI, IPEX • High Performance • QoS, Web100 and QBSS • IPv6 • VoIP, International, E2E

  3. SLAC and Internet2 • SLAC’s primary internet connection is with ESnet • SLAC also has connection to Stanford • Route to CalREN/Abilene sites • Involved with several I2 Working Groups • Also experimental connection to NTON

  4. PingER • Ping End-to-end Reporting • With HEPNRC/FNAL • And many local administrators (including I2) • 32 Monitoring sites in 14 countries • Coming soon: Africa • 434 Remote sites in 73 countries • http://www-iepm.slac.stanford.edu

  5. Surveyor • Advanced Network and Services Inc • Widely deployed in Internet2 • One-way delay measurement • Synchronized by GPS • UDP packets • http://www.advanced.org/surveyor

  6. RIPE-TT • Reseaux IP Europeens (RIPE) NOC • Similar to Surveyor • UDP packets • SLAC involved in original deployment • Now production service • Working on statistical analysis with statistician from IBM.

  7. AMP • Active Monitoring Project • NLANR • Ping Monitoring • Many HPC award Sites (Internet2) • Several sites outside U.S. • http://moat.nlanr.net/amp

  8. NIMI • National Internet Measurement Infrastructure • NIMI box at SLAC since 1998 • Deploy Active Internet Measurement for ESnet (AIME) • Advanced Monitoring • Schedule tests • Detailed characterization of links

  9. IPEX • Cross Industry Working Team (XIWT) • Passive Monitoring Project developed by AT&T Research • Funded by DARPA • Hire a student if the lawyers can agree on the contract

  10. High Performance • NTON • 2.4Gbps • Large windows and multiple streams • Achieved 100MBps • Caltech • BaBar Monte Carlo Production • GSFC • GLAST Data

  11. QoS • With Daresbury Lab in UK • Internet2 Project • BaBar plans Tier-1 site at RAL • Congestion exists transatlantic US->UK • Implement CAR on Janet NY Router

  12. Qbone Scavenger Service • Less than Best Effort • Trickle data to Tier-1 sites without impacting other services • Application or Router sets bits to mark packets • Currently ignored by network • Implemeted on dorm network at two Universities

  13. Web100 • Development by NCAR and PSC • Optimize TCP parameters • Modifications to Linux Kernel • Alpha 0.2 released • Upcoming workshop • SLAC, LBL and ORNL evaluators • http://www.web100.org

  14. IPv6 • SLAC, FNAL, ORNL, ESnet • Internet2 IPv6 Working Group • Recent workshop • Most effort in the core • Deploy machines and services • Make data available

  15. VoIP • SLAC Deployed Voice-over-IP • Nortel PBX, Cisco 3640 • Inter-lab via ESnet Testbed • CERN, DESY via regular routing • I2 Working group formulating plan • Implement dialing plan

  16. International • HENP covers the whole world • ESnet International and Internet2 International Groups • Keep track of networks carrying HENP traffic. • Arena

  17. End-to-end Initiative • IEPM not particularly E • Mostly WAN • Some LAN • I2 End-to-End Initiative • Les attended kick-off meeting

  18. Summary • A lot of common ground between ESCC Community and Internet2 Universities • A lot of useful work • need to build on it • Need to implement findings better

  19. Any Questions ?
